Area Forecast Discussion National Weather Service Austin/San Antonio TX 646 PM CDT Thu Jul 29 2021

UPDATE. Showers and thunderstorms will continue over Williamson County, the Hill Country, Edwards Plateau, and along the Escarpment into this evening, then gradually dissipate around sunset with loss of heating. Locally heavy rains and gusty winds are possible.

AVIATION. /00Z TAFS/ SHRA/TSRA are dissipating as they move across the KSAT/KSSF sites. TSRA north of KAUS should stay there with no impact to the site before dissipation in the next hour or two. SHRA/TSRA northeast of KDRT will likely dissipate before reaching that site, however, will monitor radar trends for possible update there. SHRA/TSRA will redevelop on Friday. Have no mention at the sites as PROBs are low. VFR flying conditions will prevail tonight through Friday night, however brief FEW-SCT MVFR/IFR level clouds are expected early Friday morning. Brief lower CIGs/VSBYs are possible in SHRA/TSRA. Easterly to southeasterly winds of less than 10 KTs prevail with gusts to 40 KTs possible in and near SHRA/TSRA.

PREV DISCUSSION. /ISSUED 224 PM CDT Thu Jul 29 2021/

SHORT TERM (Today through Friday) . Convective initiation has taken place across northeast portions of the CWA. Coverage of showers and thunderstorms through the remainder of the afternoon and early evening should only remain isolated to widely scattered, focusing in a corridor of weak and broad low level convergence from the Hill Country, through the I-35 corridor between San Antonio and Austin, and eastward, as well as along any associated mesoscale boundaries. Forecast DCAPE values of around 1000-1300 J/kg could support a few storms capable of producing strong downdrafts and gusty outflow winds, similar to the microburst that occurred yesterday near Georgetown. We added this mention of gusty winds to the Hazardous Weather Outlook earlier this morning. Activity should gradually diminish around sunset, with tranquil conditions overnight.

On Friday the eastern periphery of the ridge upper level builds slightly southward, however South Central Texas will remain just far enough removed that it won't completely end rain chances. The low level flow does turn more southeasterly. Isolated to widely scattered showers and storms will be possible Friday afternoon, with the greatest chances across the Coastal Plains. High temperatures Friday are forecast to remain slightly below climatological normals for this time of year.

LONG TERM (Friday Night through Wednesday) . Rain chances now extend into the weekend for the Coastal Plains the area remains on the outer periphery of the upper ridge. Meanwhile, as the ridge breaks down retreats slightly, a cold front approaches from the north on Sunday. The boundary will leave the area unsettled and better chances for showers and thunderstorms are introduced from Sunday afternoon and onward through the period. Best chances at the moment are Monday and Tuesday afternoon, as there has been better agreement with each run of the models. As for temperatures, the weekend will be hot with elevated heat index values. It is uncertain that a Heat Advisory will be necessary, but regardless of issuance, all should practice heat safety. The remainder of the week should be at or just below climate normals.
